Case report: tracheal intubation with King Vision in a patient with oral opening <1 cm

Intubation with channeled versus non-channeled video laryngoscopes in simulated difficult airway by junior doctors in an out-of-hospital setting: A crossover manikin study

“…On the other hand, novice operators, who might not be as adept with the technique of direct laryngoscopy, might prefer the King Vision channeled laryngoscopes because of its easy manipulation past the tongue for glottis visualization and a channel for tracheal guidance into the glottis [25–28]. King Vision channeled and non-channeled laryngoscopes have also been described for use as an alternative to awake fibreoptic intubation in patients with limited mouth opening and/or neck movement [15,29].…”

“…In this study, we used the acute angled channeled and non-channeled blades of King Vision ™ aBlade ™ (King Systems, Noblesville, IN, USA) video laryngoscope, and the Macintosh styled blade of the McGRATH ™ MAC (Aircraft Medical, Edinburgh, UK) video laryngoscope. We chose the King Vision video laryngoscope because of its cost, portability and design for use in patients with limited mouth opening (≥18mm and ≥13mm for the size 3 channeled and non-channeled blades respectively [15]) and restricted neck movement. These are important considerations in the management of difficult airway in an out-of-hospital or military setting.…”

Paediatric King Vision® videolaryngoscope in a case of infantile oral mass: A useful alternative to fiberoptic bronchoscope as a first choice in paediatric difficult airway

“…This case management has also shown that paediatric King Vision ® videolaryngoscope can be considered safely in scenarios where mouth opening is greatly reduced. [2] Paediatric King Vision ® videolaryngoscope with size 1 blade can therefore be used as a useful alternative to fiberoptic-guided intubation in infants presenting with large oral mass and reduced mouth opening.…”
